Yeah, mine as well. GBBPs aren't exactly the same as GBBRs, but each GBBR doesn't run identical either. Some are far superior to others. I had a few TM pistols that didn't like hot weather, one that didn't like cold weather, but mostly they haven't been an issue. My current ones are yet to show a problem. I haven't used them in minus temperatures but I have in over 35•.
